Installed the 6 filter system on my own. Easy to do following a YouTube video and water tastes great! Thanks guys. I do think the replacement o rings should come with filters and the smaller filter wrench for the 6th stage. Anything that is needed should come with filters as it’s cumbersome to have to go buy everything separately.

Dear Stephen,
Thank you for sharing your feedback. According to our records, your order #S-505712 was placed on December 11 and successfully delivered on December 19. Please note that standard economy shipping typically takes 7–14 days.
We understand your concerns regarding shipping charges. APEC is a specialized manufacturer focused on high-quality water filtration systems and components. For orders under $49, a shipping fee is applied to help cover packaging, handling, and delivery costs. Larger companies can often absorb these costs more easily due to their scale.
To provide fair pricing and reliable service, we offer free shipping on all orders of $49 or more.
Best Regards,
Karen

Ordering and Delivery were painless
Ordering and Delivery were painless. The only reason I didn't rate 5 stars was that some of the John Guest Valves and Tees were not found via search, I had to go elsewhere to find the part number to use on your site

easy peasy
The ordering process was super easy, got the shipment fast and everything was included. The instructions were clear and very helpful.
The household water smelled better right away, minerals in the bathroom sinks are noticeably reducing so I’m certain it is helping the appliances as well.
